A simple prop, it would release heat when left in its place, with the amount of heat depending on the surrounding chill. The colder it was, the more heat it would release, but it was a one-time use only.
The greater the heat released, the shorter the duration it could last.
In such conditions, the Sun Flower could last for eight hours.
